    • The present invention relates to the field of optical imaging and therapeutics. More particularly, embodiments of the present invention provide minimally-invasive Fiberoptic Microneedle Devices (FMDs) for light-based therapeutics, which physically penetrate tissue and deliver light directly into the target area below the skin surface (FIG. 1). A preferred embodiment of the invention is a fiberoptic microneedle device comprising: (a) one or more silica-based needles capable of guiding light and comprising a length of about 0.5-6 mm, a base having an outer diameter in the range of about 100-150 micron, and a tip having an outer diameter in the range of about 5-20 micron; (b) a support member to which the needles are secured; (c) a ferrule comprising one or more holes for each of the needles, wherein the ferrule is operably configured to provide mechanical support to each needle at all or some portion of the length of the needle. Embodiments of the invention enable depth-selective and deep photothermal therapeutics and can be adapted for use with any laser-based treatment or diagnostic in which light is used to detect or treat targets under or on the skin surface.
    • 本发明涉及光学成像和治疗领域。 更具体地说,本发明的实施例提供了用于基于光的治疗剂的微创光纤微针装置(FMD),其物理地穿透组织并将光直接传送到皮肤表面下方的目标区域(图1)。 本发明的优选实施例是一种光纤微针装置,包括:(a)一个或多个能够引导光并且包括约0.5-6mm的长度的基于二氧化硅的针,具有约100的外径的基部 -150微米,以及外径在约5-20微米范围内的尖端; (b)固定针的支撑构件; (c)套圈,其包括用于每个针的一个或多个孔,其中所述套圈可操作地构造成在所述针的所述长度的全部或某一部分处为每个针提供机械支撑。 本发明的实施方案可实现深度选择性和深度光热治疗剂,并且可适用于任何基于激光的治疗或诊断,其中光用于检测或治疗皮肤表面下或皮肤表面上的靶标。
